CONCORD, New Hampshire (CNN) – New Mexico Gov. Bill Richardson called on his fellow White House hopefuls Tuesday to cease “negative campaigning” right before he filed for the New Hampshire primary.

“You see how some of the candidates in our own party are starting to get negative,” Richardson said. “We’re not going to do it. We’re going to talk about the issues.”

“To all the Democratic candidates, let’s stay positive,” Richardson said. “Let’s get rid of all this negative stuff that I’m seeing.”

Richardson then singled out Sen. Barack Obama, D-Illinois, and former Sen. John Edwards, D-North Carolina, for their critical remarks of Sen. Hillary Clinton, D-New York.

“I’ve become very concerned about the negative tone of the campaign,” he said. “I think that Senators Obama and Edwards should concentrate on the issues and not on attacking Sen. Clinton.”

“The differences on the issues should be highlighted, but personal attacks I believe should not take place,” he said.

In recent days, Obama and Edwards have spoken out against Clinton’s decision to accept contributions from lobbyists. Richardson defended Clinton and reiterated that calling her “integrity into question,” was unnecessary and “personally negative.”

“There’s going to be plenty of time to get negative with the Republicans but now is not the time to start food fights,” Richardson said.

Its true JE/Bo they didn't get a knock down punch out there whimps...thumbs up to Bill R.Hillary was sound ,and I could tell she is tired of there nonsense,when they should be running there campaign,strong and confident.

If posters here think Governor Richardson is angling for a VP shot, then the entire Democratic Party is angling for a concession speech in 2008 and four more years not in the White House. Read your history folks I the last 100 years only two Senators have been elected to the Presidency – Warren Harding and John Kennedy. 4 out of the last 5 Presidents were Governors. I guess 12 years out of office will make the Democrats serious for 2012.

I agree with Governor Richardson. If we want to win this election in 2008 we should not be putting words in the Republican mouths by being negative against our own Democratic candidates. We have a very good set of people running for the office of President. Let's keep things positive from now on. I am leaning towards one candidate but if he continues to be negative, he will not get my vote.

Obama and Edwards are losing and so attacking Clinton. The Republicans are doing the same thing to their front runners. Richardson is correct, talk about the issues! Both Obama and Ewards ironically said they weren't going to get negative. Obviously they're the flip floppers and weak.

Richardson's comments made me look twice....hey maybe he can be Hillary's V.P.

Edwards always gets negative, and Obama the guy who spouts Hope is full of crap and where he is now because of his color, not dispite it. Plus dude, your Mom is white, she raised you alone so give her some respect.
